According to research, at the age of 20, collagen is already aging and losing, and its content is decreasing year by year. At the age of 25, the tissue composed of collagen and elastic fibers will gradually lose elasticity. At this time, fine lines around the eyes will gradually appear, the luster, moisture and elasticity of the skin will begin to decline, and the skin will begin to have problems such as dryness, yellowing and wrinkles.

Maintenance suggestion

On the one hand, collagen can be supplemented from the outside. Eat more foods rich in collagen in daily diet, such as pigskin, beef tendon, fish and so on. However, the absorption of collagen in food is limited, and the utilization rate is less than 5%. If necessary, you can choose to take some nutrients such as collagen peptide and protein powder.

On the other hand, we should pay attention to skin protection, especially sun protection, because ultraviolet rays will lead to the decomposition and denaturation of collagen and elastin, resulting in "photoaging". It is recommended to apply sunscreen before going out and bring a sunshade or hat when going out.
